I am looking for a gearbox that is original to an OC Type (1926/27) or a compatible Douglas replacement. The OC (Doug’s input) used a "UG" prefix box, as did TT, and SW types. I would prefer conventional road ratios (YG prefix (DT type) has close ratios) but I would consider what you have. TG and VG prefix case numbers should work (originally wide ratio) and SG (close ratio).

I will also require a clutch if anyone can provide that with or separately from a gearbox.
